EasyVr, use the volume to monitor arduino


We have as project to move an electric train with an Arduino Uno board. To do this we have to use the module EasyVr, the more the volume is high, the more the train slow down. Wo don't know how to acquire the volume from the microphone if it's possible. If you have any idea it would help us a lot.

Thank you in advance.

What you ask is possible. Go to this link: EasyVR 3 Plus Shield for Arduino - COM-15453 - SparkFun Electronics it has all the information you need. The output is async so you will need to either use a serial port or software serial pm the UNO.
Good Luck & Have Fun!
